LOCTITE ABLESTIK NCA 2286

LOCTITE ABLESTIK NCA 2286 dual cure  acrylic adhesive is designed for use in active alignment applications in camera module assembly. It has been formulated to a high viscosity and thixotropy to enable higher aspect ratios of dispensed adhesive, thus allowing for easier adjustments for the final assembly. This material jas a very high dispense aspect ration and is engineered to meet the high reliability performance requirements for the optoelectronic / semiconductor industry.

LOCTITE ABLESTIK NCA 2286 is black in color to prevent light penetration into the final assembled device. It is designed to achieve fast cure response at low temperatures and good depth of cure after UV radiation. This product also contains a secondary thermal cure mechanism for applications with shadowed areas where light is unable to penetrate. It is a camera/sensor market material that is not expected to pass very harsh reliability requirements.
